TimeStamp

Modification time stamp. Specifies the date/time this vignette was last modified.

If attribute::UseLastModified is set, the most recent vignette::TimeStamp and catalog::TimeStampvalue of the vignette and all materials involved in the request is returned in the HTTP response as a last-modified header.

catalog::TimeStamp is also used for catalog-based cache validation (see [attribute::CacheValidationPolicy](../../../../../ir-api/material-cat/image-rendering-api-ref/c-ir-material-catalog/c-ir-attributes-reference/r-ir-cachevalidationpolicy.md#reference-2d71679733474d8aa116db6ceba87fa4)).

Properties

Date/time value in Java format. Can be either the integer number of milliseconds since midnight, January 1, 1970 UTC/GMT or a date/time string value with one of the following formats:

mm/ dd/ yyyy hh: mm: ss zzz

mm/ dd/ yyyy hh: mm: ssGMT offset

• hh is in the range 0 to 23.
• zzz is a 3 or 4 character time zone code such as ‘GMT’ or ‘PST’. Daylight Savings Time must be accounted for in the time zone code (for example, ‘PST’ for Pacific Standard Time, versus ‘PDT’ for Pacific Daylight Savings Time).
• offset is a time zone offset in hours or hours:minutes, relative to GMT. For example, ‘PDT’ is equivalent to ‘GMT -7’.

All elements of string formatted date/time values must be present. If the date/time value is not formatted correctly it is ignored and the modification time of the catalog.ini file will be used instead.
